"You're always trying to get better, you're always adjusting," Nill said. "But I think the most important thing is you hire good people. They've got to grow into what they're doing. Sometimes they're smarter than me. They're there to challenge me, and they do that. It's an important part of the business. We've been together a long time, a lot of us. They've come together, they're hard-working, they're dedicated, and I always tell people they make me look good. That's what they do."
